Definitions
- the invention relates to a connecting hook for the detachable connection of two components, wherein the fixed connecting hook on a first component can be placed over a profiled component of a second component, partially overlapping this component and lockable on it.
- Connecting hooks of this type are required to a large extent, in particular in scaffolding, in order to be able to connect scaffolding frames, covering platforms, spars, struts and similar components to one another safely and quickly and to release them again, in particular in the case of scaffolding consisting of prefabricated components. While the spatial shape of the first component at the connection point for the connecting hook is relatively arbitrary and only its secure attachment has to be ensured, the component of the second component overlaid by the connecting hook is usually a cross bar or a short bracket a scaffold frame with a constant cross-section adapted to the hook opening of the associated connecting hook.
- connection hooks which are required in very large numbers, in such a way that the basic equipment is made from a workpiece that can be produced in a highly productive process, particularly in the Extrusion process, and can be easily assembled with components, which in turn can be made cheaply in large quantities or consist of standard commercial parts.
- the object is achieved in that the connecting hook is formed in cross section as a hollow profile piece, that two flat webs parallel to the surface are provided on the hollow profile piece, which, spaced apart, include a flat securing pawl that the securing pawl with the
- the component can be brought into a form fit when it is pivoted or shifted between the webs, the cross section of the component is locked in a hook opening formed on the webs, and the webs are connected by at least one belt strip and this is profiled in this way, that it forms a contact surface which is perpendicular to the cross section of the hollow profile piece and the surfaces of the webs in such a way that it is suitable for the flange-like fastening of the connecting hook to the first component.
- Such a connecting hook can be produced very cheaply from hollow profile pieces cut out to the longitudinal axis of an extruded profile, the webs being able to be unconnected on their side opposite the belt strip, but as a rule also being connected to one another there, so that the hollow profile piece has a closed cross section .
- the arrangement allows the securing pawl to be designed as a simple stamped part; it can be attached to a simple, fixed ne standard pin existing knuckle can be pivoted. All parts required for the connecting hook can be produced cheaply in this way.
- the connecting hook must be securely and rigidly attached to the first component with little effort. This is facilitated if the contact surface is kept substantially flat and is also designed in such a way that the edges of the contact surface can be welded to the first component, for example if it enables a fillet weld to be made. A sufficient weld seam length can be achieved if the contact surface in the cross section of the hollow profile piece appears as a belt surface widened compared to the rest of the profile.
- the coupling of the two components by means of the connecting hooks is generally already extremely stable because the connecting hooks are held in their position by the weight of the first component.
- the security of the connection is improved if the positive locking of the securing pawl can be locked in a frictionally locking manner with the component.
- Such a frictional engagement is easy to produce if the securing pawl can be pivoted about an axis which is stationary in the webs and which is parallel to the longitudinal axis of the component, a wedge-shaped pawl edge being formed on the securing pawl in a particularly advantageous embodiment such that it when the securing pawl is pivoted, the cross section of the component is locked in the hook opening and, in this position, a wedge action creates a frictional connection between the pawl edge and a base surface of the component.
- a short cam can also be formed on the securing pawl in such a way that the securing pawl locks the cross section of the component in the hook opening when pivoted and even in this position by a between the securing pawl and the internal Neren contact surface of the belt strip is lockable wedge lockable. It is understood that such a wedge is arranged to be deflected. While the use of a safety device which is brought about by means of a wedge is best suited to trapping short cams or the like on the molded edges provided on the component by the safety catch, the safety catches, which are optionally equipped with long catch edges, are provided for locking that which is to be locked To fix the component in its entire cross-section in the hook opening.
- the locking pawl can also be actuated here by striking with a suitable tool if a striking edge is provided on the locking pawl on which the locking pawl can be driven in its closing direction, and in particular if the striking edge on the webs of the connector ⁇ manure hook is over, as long as the components are still unconnected. Disassembly is also carried out here using a striking tool if at least one further striking edge is provided on a latch region containing the latch edge.
- a secure fixation of the component is achieved in particular in that a short retaining edge opposite the securing pawl is provided on the hook opening, which forms a further positive connection of the connecting hook with the component when this is overlapped by the hook opening, so that the cross section of the component is designed as a carrier on two supports and is held immovably.
- An arrangement in which the shape of the hook opening is partially congruent with the shape of the cross section of the component is effective in the same way, namely in the part which is only used for the installation but not for the implementation of the component; the effect can be further improved if the hook opening is dimensioned such that the congruent contours of the hook opening and the component are pressed together with a slight press fit.
- the invention provides a connecting hook which nevertheless allows a stable and secure connection of two components to be produced if inexpensive, highly automated production is specified and can be used successfully even in the case of construction scaffolds which are particularly high quality in terms of safety technology.
- the invention is explained in more detail below with reference to the drawing in an exemplary embodiment. Show it
- FIG. 1 shows a connecting hook according to the invention in a stereometric representation
- FIG. 3 shows the connecting hook of FIG. 1 in a front view and a top view, the safety catch being omitted in the top view
- FIG. 4 shows the arrangement of a connecting hook according to the invention on a first component
- Fig. 6 a slightly modified compared to Figs. 1 to 3
- the extruded hollow profile piece 1 has an approximately T-shaped cross section 10, which essentially consists of two parallel webs 11 and a belt strip 12 put together; the webs 11 are together on their side opposite the belt strip 12 Compound material, so that the cross section 10 is designed as a closed hollow profile.
- a downwardly directed hook opening 13 is cut out, which is dimensioned such that the cross section A of a component B (FIG. 5) which can also be produced as an extruded profile can be covered.
- an upper contour 13a of the hook opening 13 is shaped such that it lies flat on a corresponding, upward-pointing contour AI of the component B, if one disregards some of the grooves A2 which interrupt the closed contour AI, which is shown in the example of component B serve to increase the surefootedness, because these components B are also to be used here as ladder rungs.
- the curvature of the contour 13a is expediently dimensioned such that it can form a slight press fit with the component B.
- the component B is fixed in place on a (second) component omitted in the drawing.
- the belt strip 12 is wider than the total width b (FIG.
- a relatively large contact surface 12a which rests on the first component BE to be connected (FIG. 4) and is fastened to it with a weld seam, which here covers part of the edge 12b of the belt strip 12, but possibly also that complete border 12b.
- the contact surface 12a is perpendicular to the surfaces of the webs 11 and the cross-section 10 and is flat here; however, it can also be curved if only the border 12b, which abuts the component BE in the form of an edge, can be welded to it.
- the locking pawl 2 is about an axis 14 that is fixed on the webs 11 above the hook opening 13 (FIG . 2), for example a bolt, can be pivoted and, moreover, is formed as a flat piece of sheet metal and can thus be produced with a simple cutting tool without any problems.
- the fixed axis 14 is the Longitudinal axis of component B parallel, so that the pawl 2 can be pivoted into the area of the hook opening 13.
- a wedge-shaped pawl edge 21 is provided on the securing pawl 2, which generates a static friction force on a base surface A3 of the component B when the securing pawl 2 is pivoted clockwise under the component B covered by the hook opening 13.
- component B is first connected to the connecting hook in a form-fitting manner by means of a pawl region 20, and this form-fitting connection is ensured by the frictional connection between the pawl edge 21 and the base surface A3 Locking pawl 2 drawn approximately in the position in which it is when the component B is securely locked in the hook opening 13; a striking edge 22 (FIG. 1) is just flush with the upper edge of the webs 11. This striking edge 22 is otherwise overhanging on the webs 11, so that it is clockwise in the closing direction S (FIG. 2) with the help of a blow ⁇ tool can be driven.
- Another striking edge 23 is used for dismantling and can be driven for this purpose with a striking tool in the counterclockwise direction.
- a somewhat modified embodiment is outlined in the basic scheme in FIG.
- the locking pawl 2 ' is designed here in such a way that the base area A3 of the component B is not underpinned, but a short collar A4 approximately half the height on the component B, so that instead of the pawl region 20 only a correspondingly short cam 24 ' is provided.
- the collars A4 located symmetrically on both sides on the component B are consequently on the one hand on the cam 24 ', and on the other hand each on a retaining edge 15 which is formed on the two webs 11.
- the component B in the hook opening 13 is underpinned like a support on two supports: a support becomes the retaining edge 15, the other of the pawl edge 21 or the cam 24 '.
- the locking pawl 2' of FIG. 6 is driven by a wedge 3 which lies between the locking pawl 2 'and the (inner) contact surface - Before the belt strip 12 can be knocked in and in this way in turn secures the positive connection brought about by means of the hook edge 15 or the cam 24 'in connection with the frets A4 by means of a frictional wedge connection.
- the wedge 3 protrudes at the top and bottom of the webs 11, so that it can be easily driven in and also removed again.
